I believe it's this one! https://www.costco.com/cuisinart-immersion-hand-blender-with-storage-bag.product.100779133.html

Yeah the stick is the motor and is connected from the top

I have a 3-cup Cuisinart food processor with immersion blender and whisk, got it for $30 at costco this past November.

It's fantastic, small but big enough, and I use all the attachments at least once a week
